Welcome to Holographic Memory Cards. Holographic memory storage is a potential extremely high-capacity data storage technology, versus currently used hard drives and DVDs. These current storage technologies rely on individual bits being stored as distinct magnetic or optical changes on the surface of the recording medium. Holographic memory cards overcome this limitation by recording information throughout the volume of the card. Holographic memory cards can also record multiple images in the same area utilizing light at different angles.

Additionally, whereas hard drives and dvds record information a bit at a time in a linear fashion, holographic storage is capable of recording and reading millions of bits in parallel. This enables data transfer rates much greater.

From a Wikipedia source, Optware claims that the card will hold 30GB of data, have a write speed 3 times faster than Blu-ray, and be approximately the size of a credit card, and would cost about $1 US.
